Newtons 4th law of motion :-
A book remains in the state of rest and covered with dust until and unless internal and external exams appeared and then the speed of turning pages is directly proportional to the syllabus covered and the tension in the mind remains constant

Density of the object is equal to the density of liquid so it will float half-submerged in the liquid.

45:05 when the object and the density of water is same the object will neither be pushed up or pushed down , it will remain in the same position we hv kep it. *For example*- if we hv kept the object on top of the water it will float and if we put object on the base of water it will sink.. hope it helps u🤝👍

Sir, You are teaching 100%better than my school teacher
Newton's 4th law says that every book continues to be in rest until and unless interal or external exam appears and speed of page turning is directly proportional to the syllabus to be covered and tension in the mind remains constant .
Edit : Hey friends I'll be in 11th in some Months so being senior I wanna give u some advice for 10th
I) Don't play games too much .
II) Get deeply in the chapters to understand the topic ,,,,First complete NCERT then do any supplementary
III) Don't take Hindi and English so easy that it destroy your percentage ...
IV) Take COmputer Science or IT as joke ...
Edit 2: Yesterday I got my term 1 marks I got 39/40 in science because of you sir ....Very very thank You sir ..
Edit 3: I got my 10th result and scored 97.2% .. It was all because of you sir .. I request you guys to respect your teachers even if they are your school teachers .... Respecting teacher is very important

When the density of object is equal to water,so it will half submerged in water but didn't sink in it.

Question was that what will happen to the object if its weight is equal to the bouyant force of watet.

58:15 it will sink because the density of substance is greater than the density of water(buoyant force is depends upon density so the force applied by object is more than the force of liquid)

Density is a measure of how heavy something is compared to its size. If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float. Density is a characteristic property of a substance and doesn't depend on the amount of substance😁😘

If the density of an object is equal to density of liquid, it will float half submerged in the liquid. 😊
45:04, if density of both object and fluid is same then a balanced force will apply and the object will neither be fully float nor fully sink

The object will neither sink nor float, it will be balanced,
Perform this activity: take a safety pin📍and water 💦 in a glass.
Observation: You will observe that safety pin is neither sinking nor floating.
Hope it helps.
If it's density is greater than water it will sink

Answer: If the density of the object is equal to the density of the liquid, the object when placed in the liquid would have neutral buoyancy. The object when placed in the liquid would sink until it was submerged and then would only move up or down if acted on by forces other than buoyancy.
Thank you for helping us ☺️🙂
I have very confidence on you that I will watch your video 1 day before exam and I will get full marks in science thank you sir
Q :- what happen when the density of water and the density of object are same?
Ans :- In the question density of the object is equal to the density of liquid so it will float half-submerged in the liquid.
Science is converting towards maths 😂
Yes O_o
Because it is a physics bro☺
Abhi ruko 12 tak dekho theory to dalte hi nhi oura derivation num..
If the density is equal then the half part of the object will float and half part will sink.....
Thank u so much sir
absolutely wright
my reply is also same
Yes bro you are right 👍👍👍🔥 🔥🔥
Sir same here.
If the density of the object is equal to the density of the liquid , so it will float half sub-merged(centre ) in the water...as Gravitational forceee and buyoant force are balanced in nature
58:00 it will sink in water
16:44
Answer is 9.8 m/s² (is gravity of earth .).
its accelaration due to gravity *
Good
58:20 if the density of object is more than1 it will be sink in water because it has greater density than water
44:50 object will remain at a position where it was left untill an external force is Applied

density of the object is equal to the density of liquid so it will float half-submerged in the liquid.
Can you explain,why?
In the question density of the object is equal to the density of liquid so it will float half-submerged in the liquid
45:12 answer - If the density of the object is equal to the density of the liquid, the object when placed in the liquid would have neutral buoyancy. The object when placed in the liquid would sink until it was submerged and then would only move up or down if acted on by forces other than buoyancy.
If the density of the object is equal to the density of the liquid, the object when placed in the liquid would have neutral buoyancy. The object when placed in the liquid would sink until it was submerged and then would only move up or down if acted on by forces other than buoyancy
😇🙏
nice
If an object is exactly the same density as the liquid, it will not move up or down. It will just stay right where it is (unless it is pushed around by water currents). If you put it on the surface, it will remain on the surface 🦍
45:02 if the density of object is equal to the density of liquid the object will immersed in water
Sir buoyancy will be neutral when the density of object will be equal to density of water.
45:00 If the object is of equal density it will sink into the water so that no part of the object is above the surface
You mean equal to water level😅

Last law of motion.

True
When density is equal then the object will remain submerged
If the buoyant force equals the object's weight, the object will remain suspended at that depth. The buoyant force is always present in a fluid, whether an object floats, sinks or remains suspended. The buoyant force is a result of pressure exerted by the fluid.
newton's fourth law of motion 😂😂:-
Every book continues to be in state of rest and covered with dust until and unless internal and external exam appears and the speed of the page turning is directly proportional to the syllabus to be covered and tension in mind remain constant.
Your way of teaching the student 🙌really so good..... I clear my all doubts
If the density of object and that of water is equal then the object will float half-submerged in the liquid.
